docs: def execute_command(self):
          """
          The web command runs the Scrapple web interface through a simple \
          `Flask <http://flask.pocoo.org>`_ app. 
  
          When the execute_command() method is called from the \
          :ref:`runCLI() <implementation-cli>` function, it starts of two simultaneous \
          processes : 
  
          - Calls the run_flask() method to start the Flask app on port 5000 of localhost
          - Opens the web interface on a web browser
  
          The '/' view of the Flask app, opens up the Scrapple web interface. This \
          provides a basic form, to fill in the required configuration file. On submitting \
          the form, it makes a POST request, passing in the form in the request header. \
          This form is passed to the form_to_json() \
          :ref:`utility function <implementation-utils>`, where the form is converted into \
          the resultant JSON configuration file.
  
          Currently, closing the web command execution requires making a keyboard interrupt \
          on the command line after the web interface has been closed.
